Abstract

Here, a novel photopolymer system for recording holograms is presented. The photopolymer is sensitive to red light, so it is called RPP holographic recording material. In this paper, first of all, the components in RPP, for example, photosensitizer, photoinitiator, monomer, copolymer, combiner, stabilizer, hardener, and fabrication and processing technique of RPP are given. After that, the property of exposure in RPP is studied in the paper. It is found that RPP holographic plate has several advantages over the recording materials previously reported. First, the holograms recorded in RPP plate can be processed both in dry and in wet process. Second, the plate is only sensitive to red light, the sensitivity of which is about 2 mJ/cm². The third advantage of RPP is that the holograms recorded in it have high diffraction efficiencies which are over 40% and 80% in real-time and after wet processing respectively. Last, the RPP has high resolution which exceeds 4000 pp/mm. In the study of the exposure in RPP holographic plate, other phenomena in RPP, such as, real-time effect, light- amplification and modulation of single light beam effect, are found.
